Childhood best friends to the worst of enemies in one night. Cam and Mia each broke promises they made when they were ten years old, causing a rift in their friendship. 1. Never fall in love. 2. Never hurt each other. They make a new agreement at the end of their senior year of high school. They will only see each other on Valentine's day, the day that falls between their birthdays, when their close families get together each year. Will they ever get past what happened that night that changed it all? Or will they forever drift apart as strangers?
